Embodiment Construction
[0031] The embodiments and effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0032] refer to figure 1 , the implementation steps of the present invention are as follows:
[0033] Step 1, set the burst frame format.
[0034] 1a) Generate a pilot block P of length L 1 and a data block D of length N 1 , and a periodic "data-pilot" distribution pattern P-D with length N';
[0035] 1b) Data block D 1 , pilot block P 1 and the distribution pattern P-D are sequentially multiplexed and connected to get the following figure 2 Burst frame format F shown.
[0036] Step 2, performing a demodulation operation.
[0037] Using the corresponding pilot block P 1 The received signal r P1 (k) Perform conjugate multiplication operation with its modulation signal s(k) to obtain the demodulated signal z(k):
[0038]
[0039] Among them, κ P1 ={N,N+1,...,N+L-1} is the corresponding pilot block P obtained by setting the...
